Application February 5, 1948, Serial No. 6,435 In Italy August 6, 1947Subject matter of the present invention is a cock which, for thesimplicity of its construction,

l assures a long durability of working.

Theinvention consists of an inner casing niember supported by the supplypipe which has an external circumferential groove, ,and internalvertically disposed guideways or slots, with a portion constricted toform avalve seat, a vertically movable piston provided with, external ncam surfaces and external diametrically opposite pins to engage saidguideways, and having a constrlcted part provided with an opening, avalve having a stem, one part of which engages the constricted openingof the inner casing and the other part of which engages the constrictedopening of said piston, and supports a resilient member to vengage theinner casing, an outer casing having a member in the form of a pininsert', the inner end portion and outer end por tion of the insertbeing in combination with the outerfcasing, the inner end portion ofwhich is adapted to engage the circumferential groove of the innercasing to besupported thereby, and the outer end portion is adapted toact as a handle to rotate the outer casing on the inner casing, saidouter casing having a discharge opening and inwardly extending followersto ride on the cams of the piston, whereby when the outercasing isrotated in one direction the resilient member closes the water passage,and whenvrotated in the opposite direction opens the passage.

The invention is further described in the following specication, shownin the drawings and v finally pointed out in the claim. I

Figi. 2 is a front View;

Fig. 3 is a central section of Fig, l;

Fig. 4 is a central section of Fig. 2;

|9 ofV larger diameter and having an outside groove 36. On its innerlower part, it hasitwo small vertical grooves 3| which act as guides forthe projections 32 of vthe member 251 shown in Fig. 7.- This member 25is a small cylinder with 'a 'metallic plate having a small central hole24 for the passage of the anged pin 23` having a rubber washer 2|) (Fig.6), and preferably three arcuate slots for the passage of the water.`The pin 23 has a ange 23a for the washer and a flange 23o. The member 21(Fig.- 8) is a faceted hollow Cylinder, with reduced lower end forthepassage of the water. On its inside (Fig.4), two metallic shoulders 26extend inwardly. Two small screw pins, are supported by the member 2l,the inner ends of which engage the groove 35 of the me1nber I9, and theouter ends of which` act as handles 35. When the two handles 35 aregiven a rotary motion, counterclockwise, the two shoulders 26 moveValong the two lower helicoidal surfaces of the member 25 (Fig. 7) whichis unable to rotate in consequence of the two guides 32, in theircorresponding grooves 3|, and the member 25 is forced to have a verticalmovement in a downward direction by the water pressure acting on thewasher means 20. With this movement the resilient washer 20 cannot shutthe opening of the small cylindrical flange 22 insideof the extensionI9, and so the water coming from the piping with its natural pressurepasses through the arcuate slots 3 la of the member 25, and iinallydischarges from the lower end of the member 2l. When the two handles 35are given a rotary motion, in a contrary direction, the shoulders 26 ofthe same piece are forced to run along the two helicoidal surfaces ofthe member 25, which, unable to rotate in consequence of its two guides32 entering the grooves 3| is caused to travel in an upward direction,and with it moves the resilient washer 20 connected to the member 25.This movement closes the orifice of the cylindrical ange 22, theresilient washer being pressed against the flange 22.

The cock, in its simplicity, is easily constructed, For this reason, itcan be built also with material of inferior quality assuring itsdurability. It has no Itis ways at its lower portion, and a dependentcylindrical flange forming an oric' and constructed to form a valvevseat at the upper portion of the inner casing, a vertica1ly..movableA,cylindrical piston provided at its lower surface 1with V e-Xi'iernalhelicoidal cam surfaces and `eiternal di arnetri-Y cally oppositeradially outwardly ndi'sp'o's'ed guide membersto engage said guidewaysof inner casing, and having' an inwardly xtendingipart provided withopeningsv and a central opening, a
